BACKGROUND

The present disclosure relates generally to ophthalmologic devices for implantation into the eye, and more particular to intraocular implant devices and associated power supplies for enhancing or restoring vision in humans and animals.

Many people experience impaired vision as a result of corneal dysfunction or damage, lens dysfunction or damage, or other conditions of the eye that lead to inability of light to properly pass through the eye to the retina. Various medical procedures have been developed to attempt to correct these types of problems to improve or to restore vision. For example, lens replacement procedures are often used to remove a damaged or occluded lens from the eye. An artificial intraocular lens implant may be inserted into the eye through a small incision in the cornea during a surgical procedure to replace the removed lens. Such procedures are helpful to improve conditions such as cataracts or occluded lenses.

However, such conventional procedures for replacing occluded or damaged lenses with replacement intraocular lens implants are often inadequate to restore or enhance vision of patients with corneal conditions. As light initially enters the eye through the cornea, any conditions of the cornea which scatter or block light are generally not amenable to treatment via artificial lens replacement procedures. Although many corneal replacement procedures do exist, they are often inadequate in improving or restoring sight. Additionally, such procedures require extensive healing times and may cause other complications in the eye.

What is needed are improvements in devices and methods for improving or restoring vision in patients with impaired cornea or lens tissue in the eye.

BRIEF SUMMARY

This Brief Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

The present disclosure includes a device and methods for enhancing vision in the eyes of humans and animals. An intraocular device includes a projector associated with an intraocular implant. The projector is positioned on the implant to project an image onto the retina. The projected image may provide an overlay of a wirelessly transmitted image on the normal field of view of the eye with some natural light passing through the normal cornea, resulting in an augmented reality configuration. Alternatively, the projected image may be a completely artificial image transmitted to the projector from an external source, resulting in a virtual reality configuration. The system may be used for entertainment, recreational, educational or medical purposes.

One aspect of the present disclosure provides an intraocular photoelectric power supply system (IO-PEPS) for providing power to one or more microelectronic devices implanted into a human or animal eye. The intraocular photoelectric power supply system provides an implant shaped and sized to fit inside the intraocular lens chamber after a natural lens has been removed. The implant device of the intraocular photoelectric power supply system may be inserted into the lens chamber through a small hole in the cornea utilizing conventional lens replacement surgical tools and techniques. The implant device includes one or more photo-sensors, such as but not limited to a photoelectric device configured to convert incident light into electricity, such as a photovoltaic cell. The photo-sensor or photo-sensor array is positioned on the anterior side of the implant device such that light passing through the cornea will be incident on the sensor or sensor array when the implant device is housed in the lens chamber of the eye. The incoming light irradiating the sensor or sensor array is converted to electricity, which is then available for use by other electronics included on the implant device or otherwise installed within the eye. The incoming light may be specifically tuned to a desired frequency, wavelength, quantity, etc. for optimized power generation using the photoelectric device. The generated electricity may be used immediately, or may be stored in a power storage medium such as a battery on the implant or in the eye for later use.

Another aspect of the present disclosure includes an intraocular projection device configured for implantation into an intraocular cavity formed in the lens chamber after a natural lens is removed. The projector implant device, or artificial projector lens implant, includes an implant having an anterior side oriented toward the cornea and a posterior side oriented toward the retina. An optical light emitter, or projector, is installed on the implant posterior side of the implant facing back into the eye toward the retina. The projector is operable to emit light from the implant located in the lens chamber through the eye toward the retina, thereby forming a desired light pattern on the retina. The emitted light pattern from the projector corresponds to an image to be processed by the user's brain, and may simulate a natural light array associated with a real or artificial image. The projector implant device is miniaturized such that the projector is compact enough to fit on a normal-sized lens implant in the intraocular lens chamber after removal of the natural lens of the eye.

In some embodiments, the implant includes both a projector and a photoelectric device of an intraocular photoelectric power supply to provide electrical power for the projector. The projector is positioned on the posterior side of the lens implant facing the retina, and the photoelectric array is positioned on the anterior side of the implant facing the cornea. Natural or artificial light entering the cornea is incident on the photoelectric array on the anterior side of the implant inside the lens chamber, and the electrical power generated by the photoelectric array is transferred to the projector located on the posterior side of the implant facing the retina. The generated electrical power is used to power the projector to emit photons in a light pattern corresponding to a desired image onto the retina.

Yet another aspect of the present disclosure provides an intraocular implant device configured for implantation into the lens chamber after removal of a natural lens. The intraocular lens implant device includes a projector on the posterior side facing toward the retina, a photoelectric array on the anterior side facing toward the cornea, and an external light source spaced from the eye configured to irradiate a beam of light through the cornea onto the photoelectric array. The light from the light source is tuned to provide optimal photoelectric conversion into electricity using the specific photoelectric material installed on the implant. The external light source may be operated with an intensity much higher than natural light because the light from the light source is not incident on the retina, but is rather blocked by the artificial intraocular lens implant and used for photoelectric generation of electric power for use by micro-electronics within the eye such as but not limited to the projector on the intraocular implant device.

Numerous other objects, advantages and features of the present disclosure will be readily apparent to those of skill in the art upon a review of the following drawings and description of a preferred embodiment.

DETAILED DESCRIPTION

While the making and using of various embodiments of the present invention are discussed in detail below, it should be appreciated that the present invention provides many applicable inventive concepts that are embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention and do not delimit the scope of the invention. Those of ordinary skill in the art will recognize numerous equivalents to the specific apparatus and methods described herein. Such equivalents are considered to be within the scope of this invention and are covered by the claims.

In the drawings, not all reference numbers are included in each drawing, for the sake of clarity. In addition, positional terms such as “upper,” “lower,” “side,” “top,” “bottom,” etc. refer to the apparatus when in the orientation shown in the drawing, or as otherwise described. A person of skill in the art will recognize that the apparatus can assume different orientations when in use.

Referring now to the drawings, FIG. 1 illustrates an example schematic of an eye 10, showing a cornea 12 through which light initially enters the eye. Eye 10 includes a retina 14 on the opposite side of the eye positioned to receive the incoming light. The sclera 16 surrounds the exterior of the eye 10. A lens is typically positioned in lens chamber 18. The iris 22 provides an opening allowing light to pass from the anterior chamber 24 into the lens chamber 18. Many conventional procedures are currently known for removal of a damaged or occluded lens from lens chamber 18. For example, in cataract surgery a damaged lens may be phaco-emulsified using a tool to break up the lens. The broken-up lens may then be aspirated from the eye using a negative pressure, and replaced with a liquid solution to maintain the form of the empty lens chamber 18. Following such procedures, an artificial intraocular lens implant is inserted into the empty lens chamber 18 using known tools and techniques.

The present disclosure provides a new type of implant device for installation into an empty lens chamber 18, as shown in FIG. 1. For example, as seen in FIG. 2, an intraocular implant device 40 is shown outside of the eye 10 for implantation into empty lens chamber 18 of eye 10. Intraocular implant device 40 includes an anterior side 48 positioned to face cornea 12 after implantation, and a posterior side 50 positioned to face retina 14 after implantation. Intraocular implant device 40 includes numerous technological innovations, and is operable to provide artificial sight improvement or sight restoration.

Intraocular Photoelectric Power Supply (IO-PEPS)

One aspect of intraocular implant device 40 provides an electrical power supply configured to generate electrical power for use by on-board electronics on the intraocular implant device 40 or alternatively housed within the eye. As such, the intraocular implant device 40 includes an intraocular photoelectric power supply (IO-PEPS) device.

As seen in FIG. 3, in some embodiments, intraocular implant device 40 includes a body 42 having an anterior side 48. A photoelectric array 44 including one or more photoelectric sensors is positioned on anterior side 48. Such sensors include any suitable photovoltaic or photoelectric sensors known in the art capable of converting incident light 56 received upon photoelectric array 44 into electricity. Photoelectric array 44 covers a portion of the surface of the anterior side 48 of implant device 40. Photoelectric array 44 includes at least one electrical output operable to transmit electric power to a circuit component. In some embodiments, photoelectric array 44 is coupled to a power supply 54, as shown in FIG. 3. Power supply 54 includes any suitable power converter or power storage device on intraocular implant device 40. Power supply 54 in some embodiments includes a battery configured for storing electrical power generated by photoelectric array 44 for later use by one or more other circuit components. Power supply 54 may be continuously recharging as additional incoming light is incident on photoelectric array 44 and also simultaneously distributing electrical current to another circuit component.

Intraocular implant device 40 is generally opaque when housed within the lens chamber 18 such that incident light 56 entering the eye does not pass optically through the lens body 42. Thus, all incident light entering the eye may be utilized by photoelectric array 44 for energy conversion. As such, the incident light 56 entering the eye may be manipulated to various characteristics for optimization of photoelectric conversion by photoelectric array 44. For example, in some embodiments, various photovoltaic cells used in photoelectric array 44 provide improved energy conversion efficiencies when the incident light 56 has a chrominance in a spectral bandwidth tuned specifically to the properties of the photovoltaic junctions.

Additionally, because the intraocular implant device 40 is generally opaque, and because the cornea may generally withstand greater luminance than the retina can, the incident light 56 may be further tuned to have increased luminance over natural light to further optimize energy conversion in photoelectric array 44. Thus, the incident light 56 may be generated using an external light source with modulated chrominance and luminance characteristics as compared to natural light to further improve power generation from the intraocular photoelectric power supply.

Your Eye As the Screen (YEATS)

One application of the IO-PEPS feature on an intraocular implant device 40 is to power a projector device 46, shown for example in FIG. 3, housed on the same implant device 40 or otherwise disposed within the eye 10. For example, projector 46 may include any suitable light emitter positioned within the eye in an orientation to project generated image 58 onto the retina. The emitted light from the projector 46 is incident on the retina much in the way natural light may be incident on the retina after passing through the cornea and the lens. However, in patients with damaged cornea tissue or damaged lens tissue, by the time the light entering the eye makes it to the retina the light pattern is greatly distorted or blocked entirely, causing vision to be distorted or blurred, or causing blindness. By placing a rearward-facing projector 46 on an intraocular implant device 40, an artificial image may be projected onto the retina to simulate natural light, thereby allowing a user to see the artificial image generated by the projector much like the patient would see normally using natural light. A significant difference is that, when using projector 46, the generated image 58 may be controlled to include image data from any source, so the user's vision may be enhanced or replaced entirely over the field of view available from natural light. The generated image 58 may be projected to enhance vision in a normal user or to improve vision in a patient with impaired vision.

During use, projector 46 is powered by electric power generated on-board the intraocular implant device 40 using photoelectric array 44. Photoelectric array 44 generates enough electric power to operate projector 46 either directly, or through a power supply 54. In some applications, projector 46 may be turned off remotely while allowing photoelectric array 44 to charge power supply 54. Once a sufficient amount of energy is stored in power supply 54, projector 46 may be turned on wirelessly, and photons may be emitted by projector 46 using one or more light emitters. The generated image 58 is then illuminated onto retina 14 through the eye. The retina 14 processes the incident light much like it would natural light, forming an image in the brain and allowing a user to perceive the image.

The generated pattern of photons or generated image 58 projected onto the retina 14 is generated by projector 46 using an input signal 66 received by a wireless receiver 52 in some embodiments, as seen in FIG. 3 and in an alternative embodiment in FIG. 4. Input signal 66 includes information associated with photon pattern to be generated by one or more light emitters within projector 46. Thus, the projector 46 is configured to receive a digital input signal including the image data, and to emit photons from the light projector onto the retina in a pattern representative of the image data. The input signal 66 is passed to intraocular implant device 40 wirelessly from a remote transmitter 64. The input signal 66 is passed to a wireless transceiver 52 housed on-board the implant device 40 or alternatively housed at another location within the eye. In some embodiments, wireless transceiver 52 is integrated onto projector 46 such that the two are combined as a single unit with wireless data receiver or transmission capabilities. Image data transmitter 64 includes any suitable external device for communicating an input signal 66 to intraocular implant device 40, and specifically to wireless receiver 52 on intraocular implant device 40. Any suitable wireless signal transmission protocol for transmitting digital or analog signals associated with imagery may be used for input signal 66.

Once the input signal 66 is received by intraocular implant device 40, the signal is passed to the projector 46, and the projector executes instructions associated with the signal to generate photons representative of an image to be displayed on the retina. In some embodiments, the input signal 66 corresponds to photographs, text, illustrations, videos or any other image data.

As shown in FIG. 3 and FIG. 4, in various embodiments, power supply 54 is also connected to wireless receiver 52 in some embodiments. Thus, power supply 54 may simultaneously supply power to projector 46 and to wireless receiver 52, if necessary. Alternatively, in some embodiments, photoelectric array 44 provides generated electricity directly to wireless receiver and projector.

Wireless receiver 66 may be positioned at any suitable location on intraocular implant device 40, including on a common circuit board structure with one or more other circuit components, such as but not limited to power supply 54, projector 46, photoelectric array 44 or other components. In some embodiments, one or more antennae are connected to wireless receiver 66 to enhance reception of input signal 66 from image data transmitter 64.

One aspect of the present disclosure provides a system that may improve vision over natural analog vision. For example, when natural light enters the eye, the light incident on the retina is limited by the amount of light entering through the cornea and lens. However, using projector 46, additional, higher resolution light patterns may be projected onto the retina to improve or enhance vision over natural analog vision.

Artificial Vision System

Referring now to FIG. 5, an artificial vision system includes an intraocular implant device 40 including an intraocular photoelectric power supply, including a photoelectric array 44 disposed on the anterior side of implant device 40 facing toward the cornea 12. Additionally, a projector 46 is disposed on the posterior side of implant device 40 facing the retina 14. An external light source 68 generates a beam of artificial incident light 56 directed toward the cornea. The generated artificial light 56 is produced solely for the purpose of powering the intraocular photoelectric power supply housed on intraocular implant device 40 installed in the lens chamber 18 within the eye 10. The generated artificial light 56 is tuned in both chrominance (wavelength and frequency) and luminance (brightness) to provide optimized energy conversion and electric power generation inside the photoelectric array 44. The power generated by photoelectric array 44 is used to charge power supply 54, and is subsequently used to power projector 46 to generate a pattern of photons to create a generated image 58 for irradiation of the retina 14. Thus, the only light incident on the retina 14 is the light generated by the projector 46.

An external transmitter 64 sends a wireless input signal 66 to intraocular implant device 40. Input signal 66 is received by a wireless receiver 52 on the implant device 40, and the input signal 66 is passed to projector 46 to determine the pattern of generated photons or a generated image 58 projected onto retina 14 by projector 46. Input signal 66 can include data packets correspond to image data from any source, such as an external camera.

As seen in FIG. 5, the incident light beam 56 generated by external light source 68 is collimated in some embodiments to align with the opening of the iris 22 such that the light will be incident on the photoelectric array 44. In some embodiments, photoelectric array 44 is dimensioned to correspond to the surface region on the body 42 of intraocular implant device 40 aligned with the circular opening defined by the iris 22.

Referring to FIG. 6 and FIG. 7, in additional embodiments, external light source 68 may include a wearable technology including one or more light emitters spaced from the eye 10 and configured to emit light back toward the eye 10 for the specific purpose of powering one or more intraocular photoelectric power supply (IO-PEPS) devices housed in the lens chamber 18 in one or both eyes. For example, in some embodiments, a wearable eyeglass frame 70 includes a first external light source 68 a and a second external light source 68 b. Frame 70 includes first and second temples 72 positioned to engage a user's head, as shown in FIG. 7. Each external light source 68 emits a beam of artificial light back toward the user's eye 10. The beam of generated external light 56 passes into the eye through the cornea 12, and is incident on the photoelectric array 44 on intraocular implant device 40 housed in lens chamber 18. The external light source 68 includes any suitable source of light for powering photoelectric array 44. The light emitted by external light source 68 does not pass directly through the eye to the retina. Instead, the light is converted into electrical energy via the photoelectric array 44, and is then subsequently converted back into photons using projector 46 to project a desired pattern corresponding to an image onto the retina 14.

In other embodiments, optimized light power may be supplied to the intraocular implant device 40 by placing a rechargeable, optimized light-power source 68 on the inside of a rechargeable epi-corneal or extraocular device, such as but not limited to a scleral contact lens. This allows the device 40 to receive power even when the user's eye 10 is closed. These extraocular power sources may selectively comprise a camera 64 b and photoelectric array 44 on the front. These optimized light power sources may be necessary for situations in which the photoelectric array 44 is not capturing a sufficient amount of energy to power the intraocular device 40. Thus, these periods of intensified charging may allow the intraocular device 40 to receive sufficient energy to recharge the internal power supply 54 on the device 40.

As shown in FIG. 6, the image generated by projector 46 may come from many different sources. In some embodiments, transmitter 64 a includes a mobile device such as a cell phone, laptop, tablet computer, television, or other external electronic device. In some embodiments the transmitter 64 a is a video camera which transmits a video feed. Transmitter 64 a may include locally stored image data to be used for input signal 66. Alternatively, transmitter 64 a may connect dynamically to a remote image storage database 76 via a network, or cloud 74 to access content for input signal 66. In some embodiments, digital image content, such as movies, images, etc. are streamed from a remote database 76 via a network 74 using network signals 78 to provide access to image data for input signal 66.

Referring further to FIG. 6, in some embodiments, an external camera 64 b is also configured to produce an input signal 66. The camera 64 b is positioned to acquire image data associated with the camera's field of view. The camera 64 b may be local to a user, for example may be installed on eyeglass frame 70, or the camera 64 b may be remote such that the field of view of the camera is not in the vicinity of the user. The artificial vision system allows a user to dynamically change the input on projector 46 such that the projector 46 may select to display an image pattern associated with input signal 66 from first transmitter 64 a or alternatively from camera 64 b. In additional embodiments, camera 64 b may instead include a second transmitter such as a cell phone, laptop, tablet computer, television, or other external electronic device. In some embodiments, projector 46 includes multiple input channels, and is selectively operable to display image data associated with each separate channel, thereby allowing a user to switch between input signals from different external image data sources.

Non-Medical Uses

The above-referenced devices may also be utilized for non-medical applications such as consumer entertainment, professional vision augmentation, virtual reality content generation and display, military applications, or other non-medical applications. For example, in some embodiments, a user with an intraocular implant device 40 installed in one eye is able to selectively turn on the device to receive image data from any external source via input signal 66. The user may be able to maintain a natural lens in the second eye to continue to rely on natural analog vision when not using device 40. As such, the intraocular implant device 40 provides an implantable brain-machine interface capable of delivering digital image content to the user directly through an image projected directly onto the retina 14. The image may be manipulated in many ways by projector 46 that are not possible via standard analog light transmission through the cornea and lens. This makes enhanced, augmented and artificial vision possible.

Medical Uses

The above-referenced devices may also be used in medical applications for sight restoration or sight improvement. In such medical applications a patient may receive an intraocular implant device 40 in the lens chamber of each eye. The patient may then utilize a wireless transmitter 64 to transmit image data from an external source to each intraocular implant device 40. The transmitter 64 includes a camera oriented toward the user's local environment in some applications to simulate natural vision. Alternatively, transmitter 64 includes an auxiliary input from some other source of digital image content, such as computer, mobile phone, tablet or other source. Medical patients with conditions such as cornea damage may primarily rely on the intraocular implant devices 40 to provide artificial vision where natural analog vision simply is no longer possible due to the inability of light to properly enter and pass through the eye to the retina.

The present disclosure further provides associated methods of modifying, improving, restoring, augmenting or restoring vision in humans and animals using the previously described devices and techniques. For example, a method of restoring vision in an eye comprises the steps of: (1) providing an intraocular implant device including an anterior side and a posterior side, a photoelectric array on the anterior side, and a projector on the posterior side; (2) positioning the intraocular implant device in the lens chamber of the eye such that the photoelectric array faces the cornea and the projector faces the retina; (3) illuminating the photoelectric array with input light from an external light source; (4) converting the input light into electrical energy via the photoelectric array; (5) powering the projector using the electrical energy converted by the photoelectric array; and (6) projecting photons generated by the projector onto the retina, wherein the projected photons correspond to digital image data received wirelessly by the intraocular implant device from a remote transmitter. The method may further comprise sending a wireless input signal to the projector from an external transmitter, wherein the wireless input signal contains image data; emitting photons from the projector in a pattern representative of the image data; providing an external light source positioned to emit light towards the photoelectric sensor; receiving the light in the photoelectric sensor; converting the light into energy; and powering the intraocular implant device with the energy.

Referring to FIG. 8, an additional embodiment may utilize multilayer (multi-junction) photoelectric cells 120. The multi-junction photoelectric device may comprise layers of stacked photoelectric p-n junctions, wherein each junction is receptive to a specific bandwidth of light frequencies and permits other bandwidths of light to pass through. A first layer comprises an incident light surface 124. An incident light surface 124 is selected to allow photons which have an energy level below a first specified frequency to pass through the incident light surface but captures photons having an energy level above the first specified frequency. A second layer 126, positioned below the incident light surface is selected to allow photons which have a second energy level below a second specified frequency to pass through the second layer, wherein the layer captures photons at a frequency between the first specified frequency and the second specified frequency. In this manner, a plurality of layers 124, 126 may be stacked to capture light within a large spectrum. The layers 124, 126, 128 are stacked in descending magnitude of frequency, which allows light energy corresponding to a receptive frequency of each junction to be captured by each individual layer. This configuration provides for energy capture that is optimized in the frequency band of each individual layer and higher overall efficiency of energy conversion.
